A polythene bag making machine is an industrial system that automates the conversion of polyethylene films (HDPE, LDPE) into various bag types. It operates by unwinding plastic film rolls, then heat-sealing, cutting, and stacking them into finished products like shopping bags, garbage bags, and industrial liners.
Key Features & Technical Specs
Material Compatibility: Optimized for compostable and bio-based polymers, as well as traditional PE variations like High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), and Linear Low-Density Polyethylene (LLDPE).
Energy Efficiency: Main motors are frequently driven by inverters (VFDs), which regulate speeds for stability and can save up to 30% on electricity.
Automation: Features like automatic roll-changing, auto-tension control, and rotating dies ensure uniform film distribution and minimize manual labor.
Durability: The extruder screw and barrel are typically constructed from nitrogen-treated alloy steel for long service life and high wear resistance.
